The utility model discloses an assembly structure design benefit, secondary coil cover primary totally, prevent that secondary coupling just from getting the problem that tightly leads to the fact the magnetic leakage inadequately, the bulky of transformer has been reduced widely to two O type magnetic cores of adoption and two sets of secondary coil's cooperation structure, convenient assembling, and conveniently install the radiator additional, and improved the performance of transformer, prolong the life of transformer.

Description

A kind of bimag high frequency transformer
Technical field
The utility model relates to transformer technology field, particularly relates to a kind of bimag high frequency transformer.
Background technology
Power switch power source big or middle has a very wide range of applications at industrial circle, and high frequency transformer is as the important part of Switching Power Supply.The quality of its performance directly has influence on the performance of high frequency switch power complete machine.The feature of high frequency transformer is the pulse voltage of primary coil input after the copped wave of HF switch pipe, through transformation, produces the pulse of low-voltage, high-current on the secondary winding, then by exporting direct current after rectifier cell rectification.High frequency transformer is one of core devices of high frequency switch power Converting Unit.
At present, conventional high frequency transformer is that then secondary coil is again around on primary coil by primary coil first around on magnet ring, because primary coil is many, secondary coil is few, and secondary coil can not cover primary coil completely, cause primary and secondary to be coupled tight not, leakage field is large; In addition, because secondary coil is by high frequency big current, necessary overstriking wire diameter, conventional many shellac varnishes envelope curve twists together, and lead-in wire is stayed length, directly receives on rectification circuit, thus causing the volume making transformer to install radiator additional greatly, not easily, temperature is higher, the defect that loss is large.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, proposes a kind of bimag high frequency transformer.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of bimag high frequency transformer, comprise flat end tab, a pair magnetic core in O type is provided with above described flat end tab, described magnetic core while be arranged with the telescopic skeleton for coiling, described skeleton is arranged with primary coil; Also be provided with the A group secondary coil for winding secondary coil and B group secondary coil above described flat end tab, described A group secondary coil and B group secondary coil are in " several " font, and two magnetic cores coupling correspondences are placed on the flank of both sides secondary coil.
Preferably, described magnetic core is made up of a pair C shaped iron core, and the end between two C shaped iron cores is provided with cushion block, and the outer rim of two C shaped iron cores is fixed by the colligation of iron core strapping.
Preferably, described flat end tab has outside flat end tab and draw installation fixing hole, transformer fixing hole, transformer location and installation hole and transformer secondary coil installation fixing hole.
Preferably, the back side of described flat end tab is by heat conductive insulating cloth or heat conductive insulating plate installation of heat radiator.
Compared with prior art, assembly structure design of the present utility model is ingenious, and secondary coil covers primary coil completely, prevent primary and secondary to be coupled not tightly cause the problem of leakage field; The volume that the two O type magnetic core adopted and the fit structure of two groups of secondary coils reduce transformer is widely large, easy to assembly, and conveniently installs radiator additional, improves the performance of transformer, postpones the useful life of transformer.

Embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figures 1 to 6, the bimag high frequency transformer that the utility model proposes, comprise flat end tab 7, a pair magnetic core 3 in O type is provided with above flat end tab 7, magnetic core 3 while be arranged with the telescopic skeleton 5 for coiling, skeleton 5 is arranged with primary coil 4, the two ends of primary coil are provided with line nose 41.Flat end tab 7 to be also provided with above for the A group secondary coil 1 of winding secondary coil and B group secondary coil 2, A group secondary coil and B group secondary coil be " several " font, and two magnetic cores mate correspondence is placed on the flank of both sides secondary coil.
Magnetic core 3 is made up of a pair C shaped iron core 31, and the end between two C shaped iron cores 31 is provided with cushion block 32, and the outer rim of two C shaped iron cores 31 is fixed by iron core strapping 6 colligation.Add that cushion block 32 separates in the middle of 2 C shaped iron cores 31, prevent core sataration.Iron core can be made up of nanocrystalline, the various material doing iron core such as amorphous or ferrite.
Flat end tab 7 has outside flat end tab and draw installation fixing hole 71, transformer fixing hole 72, transformer location and installation hole 73 and transformer secondary coil installation fixing hole 74.
The back side of flat end tab 7 is by heat conductive insulating cloth or heat conductive insulating plate installation of heat radiator.
In the utility model, A group secondary coil is identical with the structure of B group secondary coil, and every section of secondary coil is converted into by copper coin or aluminium sheet, forms a circle coil see the secondary coil in Fig. 3, figure.A group secondary coil 1 and B group secondary coil 2 are installed connecting hole 12 respectively by secondary coil through the transformer secondary coil of flat end tab 7, fixing hole 74 is installed and fixes, form the cavity that two can hold primary coil.
In addition, high frequency transformer secondary coil of the present utility model adopt large area copper coin or aluminium sheet and two edges of the flat end tab 7 of center head respectively with A group secondary coil 1, the interior edge of B group secondary coil 2 closely, magnetic core is surrounded better, and just group coil is completely contained in secondary coil, adds the degree of coupling that transformer is primary and secondary, decreases the volume of transformer simultaneously, make transformer device structure compact, easy installation, efficiency is high, safe and reliable.Meanwhile, short by the secondary coil lead-in wire of high frequency big current, be connected with large-area extraction copper coin, make caloric value little, heat easily conducts, and is easy to install radiator additional simultaneously.
